hop 1 · GPT-6 Astra · 260 wordsThe tide came in an hour early. By the time Mara noticed, the causeway had vanished beneath a sheet of pewter water, leaving her alone on the island with the abandoned lighthouse. She checked her watch, then the tide table folded in her pocket. Both insisted she had time. From somewhere above, a bell rang. The lighthouse had no bell. Her father had told her that often enough when she was little, usually after she claimed to hear one through her bedroom window. Just the buoys, he would say. Sound travels strangely over water. Now he was three days buried, and she had come to scatter the handful of ashes he had secretly asked her to keep. The bell rang again. Mara pushed through the lighthouse door. Inside, the air smelled of wet wool and extinguished candles. Footprints crossed the dust toward the spiral stairs: broad heels, a slight drag on the left. Her father’s limp. She followed them to the lantern room, clutching the small tin beneath her coat. Beyond the glass, the sea had become perfectly still. On the windowsill lay a fresh tide table. Tomorrow’s date was circled. Beneath it, in her father’s cramped handwriting, were four words: Not here. Not yet. Mara stood until her breathing steadied. Then she put the tin back in her pocket and went downstairs. Outside, the water was already withdrawing from the causeway. She waited until she could see its edges before starting across, placing each foot carefully. Halfway home, she remembered the paper and found she was still holding it.

hop 2 · GPT-6 Astra · 265 wordsEvery Thursday, someone returned a book the library had never owned. They appeared in the overnight slot: slim green volumes without titles, their pages filled with descriptions of ordinary days. A woman missing a bus. A boy finding a coin. Rain beginning during a wedding. Elena kept them beneath her desk. After thirty years as librarian, she disliked a mystery she couldn't catalogue. The seventh book described her kitchen. There was the chipped yellow bowl, the chair with its uneven leg, the basil dying on the windowsill. On the final page, Elena sat at the table while someone knocked three times at her door. She turned the page. Nothing. That evening, she ate standing up. At nine, the knocking came. Through the peephole she saw a young man holding a green book against his chest. He had her husband's ears and her own narrow chin. She had never had a son. 'Wrong house,' she said through the door. 'I know,' he answered. 'They all are, mostly.' Elena rested her hand on the lock. 'What's in the book?' 'A day we went to the seaside. You bought oranges because you forgot the sandwiches.' Behind her, the refrigerator hummed. She tried to picture packing for such a trip, being distracted, leaving lunch on the counter. 'Did we have a good time?' 'It's my favourite.' She opened the door as far as the chain allowed. He passed the book through sideways. Its corners were soft with handling. 'You can keep it until Thursday,' he said. Elena looked up from the cover. 'Would you like something to eat first?'

hop 1 · GPT-6 Astra · 259 wordsThe tide came in an hour early. By the time Mara noticed, water had covered the stepping stones and lifted the old fishing boat from its bed of sand. Her father’s watch said six. The church clock, faint across the estuary, agreed. Only the sea insisted otherwise. She stood on the jetty with a bag of groceries and watched a pair of shoes drift past, neatly tied together by their laces. They were brown leather, polished despite the salt water. Her father had owned a pair like them. Behind her, the boat knocked against the pilings. It had not floated in eleven years. Mara set down the groceries. An orange rolled free, stopped at the edge, then slipped into the rising water. She expected it to drift toward the harbor. Instead, it circled the boat once and vanished beneath the hull. From inside the cabin came three measured taps. She knew that knock. Every evening of her childhood, it had sounded against her bedroom door before her father entered to say goodnight. The water reached her ankles. Across the estuary, the church bell began striking seven, though its last note of six seemed hardly to have faded. Mara stepped aboard. The deck yielded under her weight, and she caught the cabin door to steady herself. On the brass latch she found a fresh smear of blue paint, the same color her father had been using the morning he disappeared. She wiped it with her thumb. Inside, someone pulled out a chair. Its wooden feet scraped slowly across the floor.

hop 2 · GPT-6 Astra · 266 wordsAt closing time, the library returned a book to itself. Clara watched it slide through the brass slot and land on the counter. Outside, snow lay undisturbed beneath the door. She had locked it twenty minutes ago. The book was small, bound in green cloth, and warm enough to mist her glasses when she bent over it. There was no title. Inside the front cover, someone had pasted a borrowing card. Every line bore her name, written in the careful hand she had abandoned after primary school. The dates began tomorrow and continued for forty years. The last entry had been crossed out. Clara turned to the first page. It described the library exactly: the broken radiator, the fern dying above the catalog drawers, her wet scarf hanging from a chair. At the bottom, a single sentence recorded something she had not yet done. She looked toward the history shelves. A man stood there holding his hat. Clara shut the book. “I haven’t read that far,” she said. The man lowered his eyes. Snow melted on his shoulders, falling onto the carpet without leaving a mark. “Neither have I.” She recognized his voice from a message she had saved for nine winters, though he looked younger than her brother had ever been. Between them, the book opened with a soft crack of glue. Several pages fluttered past. Clara pressed her palm against them, trying to hold her place. Her brother stepped closer. “Before you read any more,” he said, “tell me whether you want me to stay.” Under her hand, the next page was already turning.

hop 3 · GPT-6 Astra · 271 wordsOn Tuesday, the sea delivered a wardrobe. It stood upright on the beach below Mara’s house, its mirrored door facing inland. The tide withdrew around its feet without wetting the wood. Mara took a kitchen knife down to the shore. She had lived alone long enough to distrust gifts that required two people to carry. The wardrobe smelled of lavender and railway smoke. Inside hung a single yellow coat, a child’s size, with a shell in each pocket. She knew the coat. She had sewn the crooked buttonholes herself. Behind her, someone cleared their throat. A little girl stood barefoot in the shallows. “You’re supposed to knock,” the girl said. Mara gripped the knife by its blade before noticing and turning it around. “Where did you get that face?” The girl touched her cheek, puzzled. “It came with me.” For thirty years, Mara had imagined what her daughter might look like: first with missing teeth, then taller, then tired from work. This was the face she had never needed to imagine. The girl pointed to the wardrobe. “I left something.” Mara lifted the coat from its hanger. Beneath it was a damp envelope addressed in her own handwriting. She opened it. There were only six words. Don’t let her take you swimming. The girl was watching her now. “Who wrote that?” she asked. Mara folded the letter and put it in her pocket. “Someone who knows me.” She held out the coat. The girl stepped into it, lifting her hair away from the collar just as Mara remembered. Together they struggled with the buttons while the water crept up the beach.

Five hops to check the OpenAI backend before the GPT-6 Astra rooms: the new-passage rule at low reasoning effort, two hops with the 600-token budget of the Qwen rooms and three with 4096. Every hop stopped on its own, at 371 to 425 tokens, and only one spent any hidden reasoning, 22 tokens, so the Qwen rooms' budgets carried over unchanged.

How to read the rest. The track above the passages has one bar per hop; its height is the compression distance from the previous hop, so a new passage is a tall bar and an exact copy a stub at the floor. Under each passage: the hop number, the model and the word count. The run id, the token count, the stop reason and the distance metrics are inside the raw output under each hop, which the raw button opens for every hop. Nothing on this page is retyped: every passage is the model's output for that hop, byte for byte, and the colophon says how that is checked.
